Biometric based Exploder

The developed device is technically superior to the existing key-based exploder with more safety features. However, cost of the device is slightly higher than the existing device. But, considering the safety and life of human beings, cost of the device is insignificant.

Exploder is a device that triggers detonators by generating electric current in order to initiate firing of explosive charges. It is also called blasting machine which helps in safe and controlled blasting to avoid the chances of misfire. It has vast applications in rock excavation for mines, roads and other construction/demolition activities. Different types of exploders available in the market are found unsafe if it is stolen and misused by illegal nexus, militants etc. To avoid such type of misuse, the biometric-based exploder has been developed. It can only be operated by those peoples who are biometrically registered with the specific device. The device comprises of an embedded microcontroller, converter circuit, rectification circuit, safe discharge circuit, and authentication circuit and display unit. The fingerprint scanner with the help of embedded microcontroller registers authorized personnel using their finger print up to 20 numbers. Once registered, no other person can use these devices. Two types of exploder have been developed, one for underground mines and another for opencast mines. 

• Implementation of biometric-based exploder will help in controlling misuse of exploder by the unauthorized person and saving of human life.
• Application of biometric-based exploder will eliminate chance of misfire.
• Blasting operation in mines will be safe and chance of stealing of exploder will be less.
• The manufacturing industry will be benefited by commercialisation of the technology after transfer of the technology.
